Replace libmpq with stormlib

[ghost]

Currently we use libmpq to read data from the games MPQ archives. Sadly libmpq is not maintained anymore, thus it is recommended to switch to stormlib which is actively maintained.

on 400 branch is done i think we can easy merge mangos/MaNGOS@2691dba

Only partial, we need to switch both map and vmap extraction. I have added a copy of stormlib to my repository which can serve as a base for all mangos branches.

See TheLuda/stormlib@1951c14fb849a5c50a5cd1dda07a119a1ef34efd for the original import. I'll probably upgrade to stormlib 8.20 next, and then I will start adding it to the mangos-zero repository so that it can be ported to one, and master, too.
